That's all you can do is ask questions at each service you're looking at. I looked at every service that was in my area in 2002: Verizon Wireless, Sprint PCS, AT&T Wireless, Primeco (now US Cellular, at least in Chicago market), Cellular One (now Cingular Wireless, and Voicestream (now T-Mobile). I didn't like coverage of T-Mobile and plans at the time, and they didn't offer no roaming charges on nationwide at that time. Also it was unlimited weekends and not nights and weekends. That's changed now, but T-Mobile still doesn't meet my needs. Didn't like Cellular One, which has since renamed themselves Cingular Wireless. After hearing my mom and sisters' complaints with the service, they left Cingular after being in the 2 year contract for just 3 months. I looked at AT&T and didn't care for their phone selection nor thei service plans. Primeco had expensive plans and very poor coverage for where I traveled and took a pass. And they refused to get into nights and weekends plans. Verizon Wireless bought most of Primeco, but US Cellular acuired the Chicago market after Verizon already had service in Chicago from the Ameritech Cellular buyout. The choices left were Sprint and Verizon. in 2002 I looked at Sprint at their $35 plan and Verizon's $35 plan. At that time, Sprint only offered 200 minutes for $35 a month and Verizon offered 300 minutes for $35 a month. Also looking at the coverage areas of both services, I decided to go with Verizon Wireless and have been with them for 2 1/2 years. The service has held up very well for me in northern Indiana, Chicago and nearby suburbs, Rockford Illinois, and Milwaukee and Madison Wisconsin. I still look at the other services, including US Cellular, but none of them seem to meet my needs. I'd like to have more anytime minutes and have nights starting at 7pm, but the terms and conditions of other services and hearing complaints of other services keep me at Verizon Wireless. For people I know with Verizon in my area rarely complain about the service, unlike those with AT&T, Cingular, and Sprint. And US Cellular's terms and conditions are what i don't like about their service. Mandating 2 year contracts, poor coverage areas, and if you lose your phone, you get charged the original price of the phone, even if you get a replacement. At least with Verizon, if you lose your phone and don't have insurance, you can get a used phone anywhere and not have to start your contract over. If you look at new and don't have insurance, you'll get hit hard when trying to buy a new phone. I was lucky when i lost my phone and didn't have insurance, there was an "Oops" plan to get a new phone at $80, but as part of the condition of getting that phone, I had to start my contract over. It wasn't the same phone, but at least I got back to using their service again. I should mention I went to Radio Shack to get Verizon Service, and they screwed me over by refusing to offer me insurance for my phone. When I lost my phone, they had the nerve to ask me if I had insurance and I mentioned no. They didn't spend a lot of time on the phone with Verizon and tried to sell me a new Motorola 120c for $200, not counting sales tax, more than srp $179 without plan. I went to another authorized agent who spent more time on the phone with Verizon and that's where I was able to get a new phone. That's why from ym experience to never go to Radio Shack for wireless service again. I'll stick to agents that specialize in wireless phone's only.
